Summary
A brief description of the data.

Ozone profiles derived by the remote sensing group at the Rutherford Appleton Laboratory (in NCEO, National Centre for Earth Observation) from radiances measured by the Global Ozone Monitoring Experiment (GOME) onboard ERS-2. The dataset also includes total column ozone, column BrO, and column NO2. Cloud heights derived from the Along Track Scanning Radiometer (ATSR) are included to aid interpretation of the ozone profiles.

Content
The actual data being described by this document. NB, in the case of data granules, this content may just be a reference to an ingested CSML or CDML file.

Introduction

The primary product of the GOME dataset held at the BADC is ozone (O₃) profiles retrieved from radiances measured by the Global Ozone Monitoring Experiment (GOME) onboard ERS-2. Other products include column O₃, column NO₂, and column BrO as well as estimates of errors of all the retrieved variables. The retrievals are performed at the Rutherford Appleton Laboratory by the Remote Sensing Group.

The dataset contains the ozone profile retrieved along the satellite orbit. There are 20 retrieval levels between 1000 and 0.01 hPa. The dataset currently includes products from 1995 to 2003.

The retrieval algorithm may perform less well in the presence of underlying cloud. The dataset includes cloud cover information derived from the Along Track Scanning Radiometer, to help interpretation of the profiles.

Restricted Data Access

To gain access to the data you must apply for access to GOME data . This allows the Remote Sensing Group at RAL to keep track of the scientific interest in the profile data. The GOME data can be accessed through the web (using a login name) or via FTP.

Data availability and file format

The data is held in NetCDF format. Details of the contents of the files can be obtained using the ncdump utility provided as part of the NetCDF distribution. IDL routines to read the files have been provided and can be found in the software directory.

Various versions of this data are available. The standard BADC filename convention has superseded the filename convention used for earlier versions.

The BADC also holds some example images produced at RAL.

Documentation and Links to further information and references

An outline of the retrieval method and example retrievals are given in the paper Height-resolved ozone information in the troposphere and lower stratosphere from GOME.
